Product Description:
HASTELLOY® C-4RTW™ filler metal is used for the gas metal and gas tungsten arc welding of C-4alloy. The deposited weld metal has outstanding high-temperature stability in the 1200°F to 1900°F range. The weld metal has excellent resistance to stress corrosion cracking and oxidizing atmospheres up to 1900°F. It also resists a wide variety of chemical process environments. The RTW™ filler metal finish on the spooled wire promotes smooth feeding through welding equipment and reduced tip wear in contact tips.
